Application filed October 30, 1918. Serial No. 798,323.

Hartshorne, in the county of Pittsburg and State of Oklahoma, have invented certain new and useful Improvements. in Devices for Preventing Fish and Drift from Going Down Waterways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'and use the same, reference being had to the accompanying drawings,

and to the letters and figures of reference marked thereon, which form a part of this specification.

This inventionrelates to new and useful improvementsin apparatus for preventing fish and drift from passing down irrigating waterways from streams.

The invention comprises essentially an apparatus of this nature so constructed as to be automatic in its action, being operated by the flow of water and without an attendant, means being provided consisting of a float whereby trash upon'the surface of the water'may be deflected away from the passageway leading into the irrigating waterway.

The invention comprisesvarious details of construction and combinations and arrangements of parts which will be hereinafter full described, shown in the accompanying rawings and then specifically defined in the appended claims.

I illustrate myinvention in panying drawings, in which Figure 1 is 'a perspective view showing the installation of my apparatus. Fig. 2 1s a perspective view of the power wheel, part of the screening about the same being cut away to better illustrate the invention. Fig.

3 is a sectional view'centrally and vertically through the wheelr- Fig--41 is across sectional viewthrough the wheel, and Fig. 5 is a detail perspective view of one of the propelling wings of the wheel.

Reference now being had to the deta ls of the drawings-by letter, A designates the bed conduc of a stream and B one of the banks which has an openin C throu h w ich water is adapted to be for irrigation and other purposes. The wall of the bank B preferably is con- J. Anmson,

the accom- C therein leading to acanalcaved as at 0 adjacent to the opening C and curved bars D are fastened to the horizontal portion, spaced apart and secured at their ends to the edges of the opening. Swinging gates E have pivotal pins E at the ends thereof which are mounted in the plates E secured to the wall of the bank, said gates being preferably curved as shown. The curving of the gates serves two purposes, as by such a construction they will be forced up near the screenwhere they prevent fish from passing between said gates and thescreen upon the wheel. Said gates being curved as shown will tend to hold any fine trash which mightv accumulate intermediate the screened circumference of the wheel and the gate when the same is held back by the current of water passing down the screen and, when sufiicient pressure comes upon the gates incident to the trash packing in between the wheel and the gates, the latter will yield to allow the trash to pass out into the canal and be carried by the current down the latter. After the trash has passed out, the current of the down stream will throw the gates back to the positions in which they are adapted to prevent fish from passing into the canal.

A. high-power screened wheel I is mounted in suitable bearings at one end of the canal and is provided with a series of wings made up of sections K, K which are hinged to the nonswinging 'wings K at K, said wings being preferably curved slightly and adapted to fold or feather in order to ofier little resistance to the water. A space J intervenes between the wall of the canal and the circumference of the wheel in order to allow any fine trash or foreign matter which might lodge against the screen to be carried by the current past the wheel.

A suitablescreen N is mounted about the wheel to the opening leading into the canal, serving to prevent fish from entering the canal.. It will be noted that the bank of the stream adjacent to the opening into the cana'lfin which the wheel 1s located is concaved and extends out into the stream, thus tending to throw laterally-any obstructions which might come aga nst the same.

A float, designated by letter 0, made on the arc of a circle, is-mounted in front of the opening leading into the canal and is guided by the standards Q in its vertical movements and hasits lower edge project- 'ing outward beyond its upper edge, serving as a means to prevent the under going current from drawing drift or trash under it, thereby prevents clogging of the wheel and water passageway, the float holding the passing matter at bay.

Gates W of a lock and dam areillustrated in Fig. 1 of the drawings and located at any suitable distance below the opening leading into the canal or ditch and which is adapted to be closed at such time as water may be low within the stream. This obstruction of the flow of water in the stream will allow the water to flow into the canal for the purpose of irrigating fields, etc. It will be understood that, at such time as the lock in the stream is closed.

any drift coming against the float will be as shown in Fig. 1 of the drawings, means is afforded whereby, when the gates are closed, the power wheel will be at rest, not being operated automatically by the current of water and when not so operated it will prevent the inflow of water into the canal or ditch and prevent also fish from entering the canal. By reason of the curvature of the gates E, any trash which might come in contact therewith and being-carried down by the current would be deflected away from the opening which leads into the canal.

The operation of my apparatus will be readily understood and is as follows :-As the water current flows down the stream and is deflected into the canal, the power wheel will be caused to rotate and the sections of the wings will feather, thus offering little frictional resistance to the water and increasing the power upon the active wings of the wheel. In the event of any small articles of floatin or foreign matter passmg the float and odging upon the screen and collecting in sufiicient quantity to cause the gates to swing outward, the trash will pass out into the stream or current of water.

this operation, it will be noted that the B wheel will be kept clear of obstructionsat all times, as the wheel will be kept continuo usly rotated by the current of water, said wings being opened by the. inrushing current of water and, as they strike against the bars connecting the ends of the wheel, will by their rapid movement and the noise caused by their striking against said bars tend to scare the fish away. As the float is guided by the rods, it will rise upon the surface of the water and tendto prevent floatmg trash from entering the canal and the horizontally disposed curved bars D will tend to catch and ward off any driftwood which might be drawn underneath the float and prevent the same from becoming entangled, with the wheel and at such time as the gates of the canal might be closed, the drift being carried down stream. By the provision of an apparatus embodying the features of my invention, it will be noted that a simple and efiicient device is aiforded whereby driftwood, trash as well as fish will be prevented from passing into irrigating canals and which, if allowed to pass into the canals, would have a tendency to strew the fields with debris and allow fish to become stranded and decay, tending to cause unhealthy conditions as well as a loss of food supply. By the provision of the means shown and described, these objections are avoided and the apparatus will be operated automatically, tending at all times to prevent foreign matter from passing into the canals.

While I have shown my wheel and apparatus designed especially for the purpose set forth, still it will be understood that power may be transmitted from the wheel, if desired, for anymechanical purpose by suitable connections.

What I claim to be new is v 1. An apparatus for preventing fish and drift from passing into irrigating canals, etc., comprising a rotatable screened power wheel adapted to be ositioned near the entrance to the canal eadin from a stream and positioned a slight distance from the wall of the canal, bars positioned across the entrance leadin into the canal, and pivotally mounted yielding gates at the opening in the canal and adjacent to said wheel, as set forth.
